| 主机名 | 网卡类型 | IP地址 |
| controller | NAT | 192.168.220.10 |
| controller | 仅主机 | 192.168.110.10 |
| compute | NAT | 192.168.220.20 |
| compute | 仅主机 | 192.168.110.20 |
二、系统配置
controller节点
-
关闭防火墙
[root@controller ~]# systemctl stop firewalld.service
[root@controller ~]# systemctl disable firewalld.service
[root@controller ~]# systemctl status firewalld.service
-
关闭NetworkManager服务
[root@controller ~]# systemctl stop NetworkManager
[root@controller ~]# systemctl disable NetworkManager
[root@controller ~]# systemctl status NetworkManager-
关闭selinux保护
[root@controller ~]# vi /etc/selinux/config
SELINUX=disabled-
配置网卡
## NAT网卡
[root@controller network-scripts]# vi ifcfg-ens33
TYPE="Ethernet"
BOOTPROTO="static"
NAME="ens33"
DEVICE="ens33"
ONBOOT="yes"
IPADDR="192.168.220.10"
PREFIX="24"
GATEWAY="192.168.220.2"
DNS1="114.114.114.114"
## 仅主机网卡
[root@controller network-scripts]# vi ifcfg-ens34
TYPE="Ethernet"
BOOTPROTO="static"
NAME="ens34"
DEVICE="ens34"
ONBOOT="yes"
IPADDR="192.168.110.10"
PREFIX="24"
## 重启网络，是网卡配置生效
[root@controller network-scripts]# systemctl restart network-
配置域名解析
[root@controller ~]# echo '192.168.110.10 controller' >> /etc/hosts
[root@controller ~]# echo '192.168.110.20 compute' >> /etc/hosts
[root@controller ~]# cat /etc/hosts
192.168.110.10 controller
192.168.110.20 compute上述配置完成后，可进行拍摄快照、关机，克隆出compute节点
compute节点
-
配置网卡
## NAT网卡
[root@compute network-scripts]# vi ifcfg-ens33
TYPE="Ethernet"
BOOTPROTO="static"
NAME="ens33"
DEVICE="ens33"
ONBOOT="yes"
IPADDR="192.168.220.20"
PREFIX="24"
GATEWAY="192.168.220.2"
DNS1="114.114.114.114"
## 仅主机网卡
[root@compute network-scripts]# vi ifcfg-ens34
TYPE="Ethernet"
BOOTPROTO="static"
NAME="ens34"
DEVICE="ens34"
ONBOOT="yes"
IPADDR="192.168.110.20"
PREFIX="24"三、 配置Yum源
controller节点
[root@controller ~]# ls
anaconda-ks.cfg chinaskills_cloud_iaas_v2.0.3.iso
# 在/opt目录下创建两个子目录，花括号 `{}` 是 Bash 的扩展语法，允许一次性创建多个目录。
[root@controller ~]# mkdir /opt/{centos7,iaas}
[root@controller ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 is write-protected, mounting read-only
# 将ISO镜像中的所有文件提取到指定的目录
[root@controller ~]# cp -rvf /mnt/* /opt/centos7/
[root@controller ~]# umount /mnt/
-o 为只读，loop以回环设备形式进行挂载，可查阅其中内容
挂载物理光驱：直接使用 mount，无需 -o loop;
挂载 ISO 文件：需 -o loop。
[root@controller ~]# mount -o loop ./chinaskills_cloud_iaas_v2.0.3.iso /mnt
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller ~]# cp -rvf /mnt/* /opt/iaas
[root@controller ~]# umount /mnt/
[root@controller ~]# rm -f /etc/yum.repos.d/*
# 配置controller节点Yum安装源文件local.repo，指向本地文件目录路径。
[root@controller ~]# vi /etc/yum.repos.d/local.repo
